BMS Main X

Strings controller

Modular BMS for 24-1000V batteries

BMS Main X controls up to 32 batteries connected in parallel, each of them is managed by the BMS Main 2.1 or BMS Mini. It limits the charging and discharging currents of the whole battery and dynamically turns on and off the parallel batteries to keep them balanced.
